## Security Audit Checklist
|
|
|
|
### Authentication & Authorization
|
|
```javascript
|
|
// Secure JWT implementation
|
|
const jwt = require('jsonwebtoken');
|
|
const bcrypt = require('bcrypt');
|
|
|
|
class AuthService {
|
|
generateToken(user) {
|
|
return jwt.sign(
|
|
{
|
|
userId: user.id,
|
|
role: user.role,
|
|
permissions: user.permissions
|
|
},
|
|
process.env.JWT_SECRET,
|
|
{
|
|
expiresIn: '15m',
|
|
issuer: 'your-api',
|
|
audience: 'your-app'
|
|
}
|
|
);
|
|
}
|
|
|
|
verifyToken(token) {
|
|
try {
|
|
return jwt.verify(token, process.env.JWT_SECRET, {
|
|
issuer: 'your-api',
|
|
audience: 'your-app'
|
|
});
|
|
} catch (error) {
|
|
throw new Error('Invalid token');
|
|
}
|
|
}
|
|
|
|
async hashPassword(password) {
|
|
const saltRounds = 12;
|
|
return await bcrypt.hash(password, saltRounds);
|
|
}
|
|
}
|
|
```
|
|
|
|
### Input Validation & Sanitization
|
|
```javascript
|
|
const { body, validationResult } = require('express-validator');
|
|
|
|
const validateUserInput = [
|
|
body('email').isEmail().normalizeEmail(),
|
|
body('password').isLength({ min: 8 }).matches(/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])/),
|
|
body('name').trim().escape().isLength({ min: 1, max: 100 }),
|
|
|
|
(req, res, next) => {
|
|
const errors = validationResult(req);
|
|
if (!errors.isEmpty()) {
|
|
return res.status(400).json({
|
|
error: 'Validation failed',
|
|
details: errors.array()
|
|
});
|
|
}
|
|
next();
|
|
}
|
|
];
|
|
```
|
|
